However, their quality and efficacy evaluation are lacking. This study aimed to compare the quality and anti-oxidant activity of Dan Shen(Salvia miltiorrhiza Radix & Rhizoma)granule extracts with their herbal extracts.Methods: Chromatographic method was used to determine the content of 7 marker compounds in the water extracts of the herb compared to that of 12 granule extracts. Agglomerative hierarchical clustering(AHC) and principal component analysis(PCA) distinguished the herbal and granule extracts based on the content of the marker compounds. The antioxidant activities of herbal and granule extracts were evaluated by 2, 2'-azino-bis(3-ethylbenz-thiazoline-6-sulfonic acid)(ABTS), organic chemical compound 2,2-diphenyl-1-picrylhydrazyl(DPPH) and ferric ion reducing antioxidant power(FRAP) assays.Results: The herbal extracts group showed significantly higher contents of salvianolic acid B, sodium danshensu and cryptotanshinone compared with that of the granule group. This corresponded to significantly higher ABTS, DPPH and FRAP(P <.05) activities of the herbal extracts. The AHC and PCA analysis distinguished granule extracts from most herbal extracts predominantly by the content of salvianolic acid B.Conclusion: The results confirm the need for the assessment of granule products so that healthcare practitioners and consumers are better informed of their quality and efficacy.展开更多
